Personal Cooling Systems for Firefighter Use
topic
Personal cooling systems for firefighter heat stress reduction include ice vest pre-cooling before entry that reduces initial core temperature, phase change cooling vests worn under or over turnout gear that absorb metabolic heat through endothermic phase transition, and post-exposure cooling using forearm and neck ice water immersion that rapidly reduces core temperature during rehabilitation periods, with each approach targeting different points in the operational cycle for maximum physiological benefit.
Role
Provides supplementary physiological cooling strategies that complement clothing design improvements in managing firefighter heat stress burden beyond what passive clothing system optimisation can achieve, with pre-cooling and active cooling systems enabling extended safe working times under heat stress conditions by increasing the thermal capacity available before core temperature reaches hazardous levels and by accelerating core temperature normalisation during mandatory rehabilitation periods.
